Dynamic model of human heart and blood systemic circulation system

Abstract

The invention discloses a dynamic model of a human heart and blood systemic circulation system. The dynamic model is mainly used for classroom teaching in a medical college, is realistic in structure and convenient to use, and deeply impress classmates with the pressing of a simulated heart to push blood to flow in the whole circulation system. The dynamic model comprises the simulated heart, simulated blood vessels and simulated organ vascular nets, wherein the simulated heart comprises a right half shell, an intermediate partition and a left half shell; the right half shell and the left half shell are arranged on the right and left sides of the simulated heart; two partitions are respectively arranged in the middles of the right half shell and the left half shell. The dynamic model has the benefits that the structure is simple and realistic; blood circulation can be simulated without utilizing an external pressurizing device; through the dynamic model, the heart anatomical structure can be understood in a visible and operable manner, and systemic circulation and pulmonary circulation can be simulated; the dynamic model can serve as an intuitional teaching aid for showing the heat structure to students, simulating the pathways and directions of heart blood circulation, helping to understand pulmonary circulation and systemic circulation, and facilitating memory deepening and book knowledge understanding.

Description

technical field [0001] The invention relates to a medical teaching apparatus, in particular to a dynamic model of a human heart and blood circulation system, which is mainly used in classroom teaching in medical schools. Background technique [0002] The heart is one of the vital organs of the human body and is the driving force in the circulatory system. The human heart is like one's own fist, shaped like a peach, located above the diaphragm, between the two lungs and to the left. It is mainly composed of cardiac muscle and has four chambers: left atrium, left ventricle, right atrium, and right ventricle. The left and right atriums and the left and right ventricles are separated by intervals and are not connected to each other. There are valves between the atrium and the ventricle. These valves allow blood to flow only from the atrium into the ventricle, and the blood cannot flow back. The role of the heart is to promote blood flow, provide sufficient blood flow to organs...

Problems solved by technology

At present, the role of computer technology and multimedia technology in modern teaching has produced good results. However, most graphics and pictures can only represent two-dimensional information, and cannot give people a deep three-dimensional feeling, which makes students understand and memorize more easily. Difficulties, the quality o...
